Australian Open 2012 live stream

With Rod Laver at Melbourne Park to celebrate the 50th anniversary of his first Grand Slam, and Roger Federer and Rafael Nadal squaring off in a blockbuster semifinal on Thursday night, there is hardly a better time to pose the question: who is the greatest men's player of all time?

We've set up a poll in our online fan centre to get your opinion and find out who the winner is.

We had a clear winner in the best women's player of all time poll: Steffi Graf was the people's favourite with over 40 per cent of the votes. We also had a standout winner in the most recent poll about the greatest rivalry in tennis. The Roger v Rafa rivalry attracted two-thirds of the 15,500 voters.

So, get in and have your say on our latest poll, and tell us: is it Rod, Roger, Rafa or someone else?
